AIR-SHIP.

T 0 all whom it may concern.

Be it known that I, JOHANN SGHUETTE,

rigid type consists essentially of a plurality of longitudinal girdersand of rings. Each ring has the shape of a polygon, the number of thesides of which is generally determined by the number of longitudinalgirders. The rings themselves are usually internally braced by a numberof ties, which, constructed in any suitable manner couple the junctionpoints of the sides of the ring, so that it is practically impossiblefor them to be deformed. Besides the normal stresses caused by the gaspressure transmitted to them by the longitudinal girders these ringshave frequently to carry individual loads, which generally must act onsuch junction points, which are already under heavy strains, or which bytheir position are less suited for such purposes. Thereby exceptionallyheavy stresses ma be produced in some, of the rods of such rlng bodies,which may, under circumstances, lead to inadmissibly high deformationsof the rings.

In order to avoid such danger, the present invention provides that oneor several trusses are disposed within the plane of such rings in such amanner that the load is received, not as heretofore by the rin itself,but by said trusses and transmitted y the latter to any desired numberof junction points of the ring situated in favorable positions.

Owing to the peculiar character of the strains acting upon such rings ofrigid airships forces may appear, which tend to force the ties of thering or parts thereof from the normal plane. Theindividual beams of thetrusses are either partly or all preferably hinged tothe junction pointsof the sides of the ring so that they may be able to follow anydeviation of the plane of the ring.

It is obvious that the trusses may be of any desired form and may beapplied to any number of ring members and may be arranged, as desired,either at one part of the Serial No. 724,124.

ring only or at a plurality of such parts, or may be arranged along theentire circumference of the ring. Thus the individual loads affectingthe trusses can be transferred to any desired number of junction pointsof the ring which may be most favorably situated, for example, in theupper or lower part or atthe side parts of the ring, oi distributed overthe whole circumference.

In the accompanying drawings;

Figure 1 is a diagrammatic View showing the framework of an airshipthrough a section, and showing particularly one position and arrangementof the truss work of the present invention.

Figure 2 is a similar view showing a dit' ferent arrangement of thetruss work of the present invention.

Figure 3 shows a section of a ring which connects the longitudinalgirders, showing the junction point of the truss beam with the lattershinged connection thereto.

Figure 4 is a detail of one of the beams of the truss work.

Figure 5 is a transverse section of the beam shown inFigure 4..

In the drawing, a indicates the rings, 1) indicates the trusses disposedin the plane of the ring, and 0 indicates the ties for transmitting theload or loads.

In Figure 1, a one unit truss is provided, while in Figure 2, a doubleunit truss is employed. Each of the units in Figure 2 is connected tothe ring by three-part trusses, and provided with ties (2 extendingdownward to the point at which the load is connected thereto.

In Figure 3, there is shown one of the longitudinal girders e and a ringjunction point f. This View shows how the truss beam 71. is hinged orpivotally connected to the junction'point One form of beam which may beused in the truss is shown in Figures 4 and 5.
